    (This is a duplicate of a thread I accidentally started in the wrong subforum here:  https://www.telerik.com/forums/latest-ui-for-wpf-release-throws-exception-when-using-radopenfolderdialog)

    I just upgraded to the latest release of UI for WPF (2018.3.blah blah).  So far everything has been working fine.  But today I invoked a bit of my code that uses RadOpenFolderDialog.  The code is pretty simple:

                var dlg = new RadOpenFolderDialog
                {
                    InitialDirectory = Settings.LibraryFolder,
                    Multiselect = false,
                };
                var res = dlg.ShowDialog();

     

    (I have verified the "Settings.LibraryFolder" points to a valid, existing folder at the time this function is called)

    It then throws an exception.  The outer exception message is this:
        "Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an exception."

    The inner exception message is this:
        "Cannot find resource named 'BreadCrumbBarItemCustomStyle'.  Resource names are case sensitive"

    I do not now, nor have I ever had a resource of that name so I have to assume this is something inside the Telerik release that was inadvertently removed.  Can you help me?
    I don't know if it is relevant but early on in my app I use the StyleManager to set an application theme

                StyleManager.ApplicationTheme = new Windows8TouchTheme();


    Also I am *NOT* using the "NoXaml" approach

    Help...?

    Hi Joe,

    Thank you for this report. This appears to be a regression issue in our R3 release and we will include a fix for it in the internal build next week as well as in the Service Pack next month.

    Thank you, Peter.

    In case anyone else is experiencing this, I was able to work around it by choosing a different theme in my case Office2016Touch.

    I personally find the Windows8Touch theme to be more touch-friendly though so I look forward to the fix.

    I appreciate the quick reply!
